Sandy Bridge: Core i7 2600K and Core i5 2500K

Super Pi

Meanwhile Super
Pi even in its latest version has become pretty old. Never the less it is able
to show scaling to the clock speed nicely. fr]Les résultats de SuperPi varient en fonction de la fréquence du processeur et de la mémoire vive ainsi que par ses timings[/fr]

wPrime

wPrime is based on a
multithreaded algorithm to calculate the square root to up to 32 billion digits.
Therefore it is possible to put 100 percent load on every core or thread and to
see differences between architectures.
